简要总结
This study focuses on mechanisms to adapt the performance of interactive voice response (IVR) and computer assisted telephone interviews (CATI) surveys conducted in low-and middle-income (LMIC) setting (Bangladesh) and evaluates how the two survey modalities (IVR and CATI) affect survey metrics, including response, completion and attrition rates.
详细描述
Using random digit dialing (RDD) sampling technique, participants will be randomized to one of two arms : 1) IVR or 2) CATI. Participants in the first study arm will receive an IVR survey. Participants in the second study arm will receive a CATI survey. Each questionnaire contains a set of demographic questions and one non-communicable disease (NCD) module (alcohol, or tobacco, or diet, or physical activity, or blood pressure and diabetes). We will examine contact, response, refusal and cooperation rates and demographic representativeness by each study arm.

结局指标
主要结局
Cooperation Rate #1
时间窗: Through study completion, an average of one month
As defined by American Association for Public Opinion Research, cooperation rate is defined as I/(I+P+R) where I is complete interviews, P is partial interviews, and R is refusals and breakoffs
Response Rate #4
时间窗: Time Frame: Through study completion, an average of one month
As defined by American Association for Public Opinion Research, response rate is defined as (I+P)/(I+P+R+eU) where I is complete interviews, P is partial interviews, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns
次要结局
